a python-telegram-bot Unsupported url protocol

So, I was Trying To Create a Telegram Bot That By Using The PyTube Moudle, Will Download The Video To My Computer And Then Send It To The User By The send_document Function.

My Problem Is When I Need To Send The Video, I Get This Error:

telegram.error.BadRequest: Invalid file http url specified: unsupported url protocol

I've Tried It On a Regular Text File And Got The Same Results.

I Assume It's Because The Url of The File Is Breaking Some Rules of How It Should Look Like, But I Don't Know How To Fix It...

Also Here Is My Code:

import telegram.ext
import telegram
from telegram.ext.messagehandler import MessageHandler
from telegram.ext.commandhandler import CommandHandler
from telegram.ext.filters import Filters
import time
import pytube
import os

with open('C:/Users/EvilTwin/Desktop/stuff/Python/API/Telegram/Download Youtube Videos Bot/token.txt')as file:
    API_KEY = file.read()


updater = telegram.ext.Updater(token=API_KEY, use_context=True)


def start(update, context):
    update.message.reply_text(f'Hello {update.effective_user.first_name}, I\'m Roee\'s Video Downloader!')
    time.sleep(1)
    update.message.reply_text(    
    f'''
To Download Videos Please Enter:
/download + Video URL  + Format
    
    ''')

def download(update, context):
    URL = context.args[0]
    FORMAT = context.args[1]
    VIDEO = pytube.YouTube(URL)
    FILE = VIDEO.streams.filter(progressive=True, file_extension=FORMAT).order_by('resolution').desc().first() 
    VD = 'C:/Users/EvilTwin/Desktop/stuff/Python/API/Telegram/Download Youtube Videos Bot/Videos'
    FILE.download(VD)
    banned = ['/', '/-\\', ':', '?', '!', '*', '>', '<', '"', '|']
    for ban in  banned:
        VIDEO.title = VIDEO.title.replace(ban, '')
    time.sleep(1)
    DOC = f'{VD}/{VIDEO.title}.{FORMAT}'
    chat_id=update.effective_chat.id
    context.bot.send_document(chat_id = chat_id ,document=DOC, filename = f'video.{FORMAT}')
    os.remove(DOC)



updater.dispatcher.add_handler(CommandHandler('start', start))
updater.dispatcher.add_handler(CommandHandler('download', download))

updater.start_polling()
updater.idle()

If Anyone Knows How To Fix It Please Help Me....

Solution

For local file you have to use file object (file handler) instead of file name
so you have to open it document=open(DOC, 'rb')

context.bot.send_document(chat_id=chat_id, document=open(DOC, 'rb'), filename=f'video.{FORMAT}')

Documentation shows also that you can use pathlib.Path or bytes (so it needs to read it document=open(DOC, 'rb').read()) but I didn't test it.

See doc: send_document()
